Here are those two rules:
Dad's Against Daughter's Dating. Really?
Normally I'd be all up in arms about capitalizing every letter, but the reason for this is they're trying to create that D.A.D.D. idea, so I'll let it go ... this time.
I suppose there are a few ways this could have been done, but neither includes an apostrophe replacing a plural.
1. Dads Against Daughters Dating.
2. Dads Against Daughter's Dating (meaning the dad is against the fact that his one daughter is dating)
3. Dads Against Daughters' Dating (meaning the dad is against the fact that his multiple daughters are dating)
But I do have a complaint, obviously. Loyal followers of this blog will pick up on the problem here right away, because I know I did an "its/it's" blog a while back.
What this sign says, in fact, is:
Building On It Is Heritage Shaping It Is Future.
Do not use It's as a possessive or a plural. Its only job is to replace the "i" in Is.
There should also be a period, comma, or semi-colon after Heritage, but I'm kind of skipping over that.
Building on its heritage; shaping its future.
